Uh there is a 4th cat in my house

I have no idea how my SO has managed to get this cat into our house. It’s a stray that has been roaming around for weeks and she’ll come near me but if I even move an inch she’s gone.

And I wake up at 3 am with a sore throat to see this cat inside my house laying on blankets that he specifically made a bed for her with. He was the one who was irritated at me for rescuing another kitten but now Theres a 4th cat in my house... I’m guessing he felt bad because it’s freezing rain outside so he had to have spent a long time trying to get her inside. I’m rubbing off on him lmfao. I have no idea what he did, but I’ve been walking all around my house and she’s just watched. She hasn’t moved. She’s not scared of me anymore. Wtf did he do in those few hours I went to sleep before him?

I never planned on having more than 2 cats but then I found an emaciated kitten abandoned in a parking lot and nursed it back to health and now... I guess we are crazy cat people

Lord help
